Zombie pop3s (and imaps?) processes in connect state

by Christian Balzer

Hello, we've been using perdition as a pop3/pop3s/imap/imaps proxy for about four years now, first with Debian Sarge package and now under Etch. And throughout this time I've seen pop3s (and from the looks of it the same happens with imaps) processes stuck in connect, like this: --- 16836 ? S 5:31 0 120 32179 2204 0.0 perdition.pop3s 28070 ? S 0:00 0 120 32311 1564 0.0 \_ perdition.pop3s: connect 7782 ? S 0:00 0 120 32311 1564 0.0 \_ perdition.pop3s: connect 24468 ? S 0:00 0 120 32311 1568 0.0 \_ perdition.pop3s: connect 14180 ? S 0:00 0 120 32311 1568 0.0 \_ perdition.pop3s: connect 13503 ? S 0:00 0 120 32311 1564 0.0 \_ perdition.pop3s: connect --- They never die off, keep the connection open, there is no traffic and the other end might be long gone. Last trace in the logs is always like this: --- Feb 5 22:05:16 pp11 perdition[7782]: Connect: hi.mi.ts.u->203.216.5.113 --- It must be something related to the SSL'ness of these service, since I'm not seeing this happening ever for imap/pop3. Alas a lot of people do use TLS with those, so it's not a generic SSL issue. Maybe the master process could kick a child handling connections in the head after "timeout" seconds in connect state? If more information is needed I can try to provide it, but note that with a rate of roughly 35 pops per second I'm a bit weary to turn on debugging. ^_- This may or may not be related to another SSL related issue, which will be for the sake of making searches in the archive more likely to find good keywords in a separate mail.

updated IPv6 patches for perdition and vanessa socket lib

by Antonio Querubin

The original IPv6 patches I submitted earlier didn't build on Linux systems. Attached are updated IPv6 patches which have been tested successfully in inetd mode on CentOS 5. However, in daemon mode under CentOS, sometimes the spawned process will segfault. I'm still trying to determine whether this is due to a problem with the patch itself or the way I've built the RPM. Both daemon mode and inetd mode under FreeBSD seems to work reliably though so I suspect this problem is something peculiar to Linux which I've overlooked. In any case, I'm putting these updated patches out in the hope of getting additional data back from anyone running perdition in daemon mode on Linux systems. Antonio Querubin whois: AQ7-ARIN

SO_KEEPALIVE

by Rudy Gevaert

Hello, When using inetd together with perdition it is possible to set the keepalive flag. I couldn't find a way to see if the perdition daemon also does this. Or isn't this relevant? (We are using perdition behind LVS and the keepalive flag needs to be set.) Thanks in advance, -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Rudy Gevaert Rudy.Gevaert(a)UGent.be tel:+32 9 264 4734 Directie ICT, afd.

Advise in perdition with many back-end server

by Nelson Serafica

Right now my setup is like this: DOMAIN: foo.com and with some aliases perdition server (public) ---> back-end server A (private) DOMAIN: fee.com and with some aliases perdition server (public) ---> back-end server B (private) DOMAIN: fii.com and with some aliases perdition server (public) ---> back-end server C (private) I want to minimize servers and powers so I want it to be this way DOMAIN: foo.com, fee.com and fii.com perdition server (public) --> back-end A, backend B and back-end C server How can I do this using perdition? My current perdition setup has "outgoing_server <private ip>:143"" in every perdition.imap4.conf and perdition.pop3.conf. I think I need to change this to other type such as MySQL. Is this possible? Can someone guide me to this? ____________________________________________________ Tired of spam? Yahoo! Mail has the best spam protection around http://ph.mail.yahoo.com

cyrus perdtion , connections not dying

by ram

I have a 40k user cyrus server , and I am trying to scale up by trying to add a perdition server infront of this server so that we can add more servers ( Both servers dell 2950 with 8GB RAM ) But the problem I have the moment I install a perdition server is that , the number of pop connections do not seem to reduce at all once started. I had 10 connections in morning and with 15 minutes the number of connections went to 3000. And on the real server the connections are all full Usually we have around 700k simultaneous pop connections on the real servers now with perdition we have 3000+ connections How do I get perdition close connections quickly
